在Route :: model中找不到laravel 4句柄 [英] laravel 4 handle not found in Route::model

问题描述

在routes.php中使用"Route :: model"时

when use "Route::model" in routes.php

Route::model('pizza', 'Pizza');

Route::get('edit/{pizza}', 'PizzaController@edit');

如果在数据库中找不到"id"，我会收到错误消息，如何在此状态下显示自定义消息?

I receive error if "id" not found in DB, how to display custom message in this status?

谢谢

推荐答案

默认情况下，如果模型绑定失败，Laravel将抛出404错误.因此，您要做的是提供一个闭包作为第三个参数，以覆盖行为并引发其他错误:

By default, Laravel will throw a 404 error if the model binding fails. So what you'll want to do is provide a closure as a third parameter to override the behavior and throw a different error:

Route::model('pizza', 'Pizza', function()
{
    throw new ModelNotFoundException; // or NotFoundHttpException or PizzaNotFoundException...
});

请参阅: http://laravel.com/docs/routing#route-model-绑定

将其放置到位后，就可以在app/start/global.php

Once you have that in place, you can catch the exception and handle it however you'd like in app/start/global.php

请参阅: http://laravel.com/docs/errors#handling-errors

或者不引发异常，您可以使用闭包对特定页面返回Redirect响应，并带有指示错误的闪现消息.

Or instead of throwing an exception, you could just use the closure to return a Redirect response to a specific page with a flash message indicating the error.
